Jeremiah Langhorne is the chef and co-owner of The Dabney and Petite Cerise in Washington, D.C. Born and raised in Charlottesville, VA, Langhorne spent time in kitchens there before moving to Charleston to stage under chef Sean Brock at McCrady’s, one of Charleston’s most iconic restaurants. After completing a stage at Noma in Copenhagen, Langhorne returned to McCrady’s as sous chef. He worked alongside Brock for more than five years before returning to his Mid-Atlantic roots in 2013 to focus his efforts on opening his own restaurant. The Dabney opened in 2015 in D.C.’s Shaw neighborhood, serving modern American food with strong regional and historical influences, with a ten-foot-long wood-burning hearth at the center of the open kitchen.

Now in their 10th year, Langhorne and The Dabney continue to garner accolades. The restaurant has earned a Michelin star every year since the Guide’s D.C. debut in 2016, was named a James Beard Semifinalist for Outstanding Restaurant in 2025, and was named the #1 restaurant in the District by Washingtonian magazine in 2023. Langhorne received the 2018 James Beard Foundation Award for Best Chef: Mid-Atlantic.

Langhorne and his partners opened Petite Cerise, located in a historic row house in D.C. 's Shaw area, in March 2023. The all-day French bistro concept is an homage to Langhorne’s love of France and French cuisine and offers weekday lunch, weekend brunch, and daily dinner service.
